Title: Scorodite-type iron-arsenic compound particles, production method thereof, and arsenic-containing solid
Inventor: INOUE KENICHI
IPC: C22B30/04
Filed: 2010-05-12
Abstract: Provided is a scorodite-type iron-arsenic compound having good filtration performance that satisfies the criteria for elution tests (initial pH of 5.8 to 6.3) in accordance with Japanese laws and ordinances (Ministry of the Environment Bulletin No. 13) and that realizes an excellent arsenic elution-preventing effect, even under an environment of approximately pH 3 or approximately pH 7. There is an iron-rich layer having an Fe/As molar ratio of 1.24 or greater at the particle surface layer part of the scorodite-type iron-arsenic compound particles. Such particles can be obtained by further adding, before the reaction is complete, an oxidizer to a reaction process whereby an oxygen-containing gas is fed to an aqueous solution containing pentavalent arsenic ions and bivalent iron ions as scorodite-type iron-arsenic compound crystals are caused to precipitate under a pH of 2 or less (treatment A).  Moreover, these particles can also be obtained by bringing scorodite iron-arsenic compound particles having good crystallinity into contact with an iron ion-containing aqueous solution at 0 to 90°C that has been brought to a pH of 2 to 9 (treatment B).

Title: System and method of reducing risk and/or severity of pressure ulcers
Inventor: DRENNAN DENIS BURKE
IPC: A61B5/04
Filed: 2010-04-16
Abstract: A pressure monitoring method and system (10) for warning a patient or caregiver that soft tissue pres-sure has exceeded some predetermined level that over time would necessitate moving the patient to minimize or pre-vent soft tissue damage. The method and system (10) entail the use of a pressure-sensitive pad assembly (14) adapted to be applied to a surface of the patients body and generate electrical outputs corresponding to soft tissue pressure sensed at the surface. The system (10) monitors the electri-cal outputs over a preselected time period and generates a cumulative output signal (50,52) based on the electrical outputs and corresponding to whether or not the soft tissue pressure has exceeded a predetermined pressure level dur-ing the preselected time period. The system (10) generates audible and visual warnings if the cumulative output signal (50,52) exceeds a predetermined cumulative threshold un-til the soft tissue pressure drops below the predetermined pressure level.

Patent CA-2761048-A1 (CA)
Inventor: COSKUNER GOKHAN
IPC: C09K8/582
Filed: 2011-12-07
Abstract: A post cold heavy oil production with sand ("CHOPS") microbial enhanced oil recovery ("MEOR") method comprises selecting a well in communication with a reservoir having at least one wormhole and that is being subjected to or has completed primary CHOPS production and determining whether the reservoir contains a sufficient amount of a gas-producing indigenous microbe to re-pressurize a drainage portion of the well to a target pressure or to generate a target amount of gas. When the reservoir does not contain a sufficient amount of the indigenous microbe, then an injectant is prepared comprising a sufficient amount of a gas-producing microbe to re-pressurize the drainage portion of the well to the target pressure or to generate the target amount of gas, a nutrient suitable for the microbe, and a fluid base. When the reservoir does contain a sufficient amount of the gas producing indigenous microbe, then an injectant is prepared comprising a suitable nutrient for the indigenous microbe and the fluid base. Then, the injectant is injected through the well and into the at least one wormhole in the reservoir; the well is shut in until the pressure in the well reaches the target pressure or the target amount of gas is generated; and then the well is produced.

Patent CA-2761707-A1 (CA)
Title: The production of n,n-dialkylaminoethyl(meth)acrylates
Inventor: BRAMMER LARRY E JR
IPC: C07C213/08
Filed: 2010-05-07
Abstract: A method and apparatus for preparing a N,N-dialkylaminoalkyl acrylate in a continuous transesterification reaction.  The reaction involves adding alkyl acrylates such as methacrylate or ethacrylate to a reboiler mechanism and efficiently removing alcohol co-products. Because the reaction is continuous, the alkyl acrylates can be added as needed to increase output, decrease output, or fine-tune the reaction dynamics. An entrainer is used to form a volatile azeotrope which contains both alcohol and entrainer and which is easily removed from the reboiler mechanism. This method reduces the amount of entrainer needed per unit of alkyl acrylate used and eliminates any need to purify the end product from entrainer contamination of the resulting N,N-dialkylaminoalkyl acrylate product.

Abstract: A method and system for displaying three dimensional images of runways and terrain, as well as additional information, on one or more screens of an avionics display system is provided. The system merges elevation information for terrain points and elevation information for runway points by grouping runways together that are within a threshold distance of each other. For each group, a plane is calculated. The calculated plane is then projected onto all of the runways within the group. The plane may also be projected onto a subset of neighboring terrain points. The adjusted elevation created by the projection of the plane are then used in creating the images for display on the synthetic vision display. The result is that all of the runways within a group, along with their neighboring terrain, are displayed as being coplanar.

Abstract: A method for determining a limit of a phase control power range includes applying a first gate pulse to a switch at a first firing angle near the limit of the power range, sensing the conductive state of the switch after the first gate pulse, and determining the limit of the power range in response to the conductive state of the switch. If the switch remains conductive after the first gate pulse, the first firing angle may be used as the limit of the power range. If the switch does not remain conductive after the first gate pulse, the limit may be determined by repeatedly incrementing the firing angle, applying a gate pulse to the switch at the incremented firing angle, and sensing the conductive state of the switch after each gate pulse until the switch is conductive after a gate pulse.
